<p>
You can import graph data into a NodeXL workbook from a variety of sources in a variety of formats.
</p>

<p>
Imported graph data normally overwrites any graph data that is already in the workbook, but you can change this so that imported data gets <i>appended</i> to existing data instead.  Appending graph data can lead to confusing results&mdash;in particular, you can end up with multiple rows in the <a href="../WorkbookTour/Worksheets.htm">Vertices worksheet</a> for the same vertex&mdash;so this option is intended for advanced users only.
</p>

<div class="HowToTitle">
To tell NodeXL to append imported graph data to existing data:
